fix(packaging/rpm): the CLI's %files entry had wandered into %install

bf981027 added the punktfunk CLI to the spec, but its `%{_bindir}/punktfunk`
files entry landed one section too early — inside %install, where rpm's
shell dutifully executed /usr/bin/punktfunk (which doesn't exist on a
builder) and killed both rpm legs at %install ever since. Move it where it
was headed: out of the script, into %files client — which was missing it,
so the fixed %install would otherwise have died again on an unpackaged
/usr/bin/punktfunk.
